Wow, incredible. I told myself I’d stop waffling and just buy the next 800gb/s mini or studio to come out, so I guess I’m getting this.

Not sure how much storage to get. I was floating the idea of getting less storage, and hooking it up to a TB5 NAS array of 2.5” SSDs, 10-20tb for models + datasets + my media library would be nice. Any recommendations for the best enclosure for that?

[kridsdale1 → rjeli]

It depends on your bandwidth needs.

I also want to build the thing you want. There are no multi SSD M2 TB5 bays. I made one that holds 4 drives (16TB) at TB3 and even there the underlying drives are far faster than the cable.

My stuff is in OWC Express 4M2.

Are you running RAID?

[kridsdale1 → perfmode]

Yes RAID 5.

IIRC when I played KSP it was necessary to point slightly down if you wanted to reach orbit in a continuous burn, rather than waiting to burn more at perigee. Is that true in general?

(was playing with a mod that models ullage, so relighting was quite finicky)

There's a great Eager Space youtube video about it: https://www.youtube.com/watch?v=XxEy9mDeq40

For C++, `bit_cast<uint32_t>(0.f)` should be Well Defined, right? I'm curious, in C, is union-casting float->uint32_t also Perfectly Legal And Well Defined?

(I am not a C or C++ expert.)

Funny that when I reached the "Key Findings" section, my brain immediately parsed it as ChatGPT output. Maybe it's the bullet points, the word choice, or just the font...

[molave → rjeli]

I can tell technical papers influenced ChatGPT's outputs the most. Most of the articles generated using it may be regurgitated, but I can't deny how easily digestable the info is when presented that way.

[Der_Einzige → rjeli]

There appears to be a coherent effort among the general populace , conscious or unconscious, to shape discourse going forward to look more ChatGPT style in general. Words like “delve”, “crucial” etc have become more common even among real people in face to face communication and in record time.

Much as I find it overly formal, I support it on the grounds that it frustrates attempts to “detect” if LLMs are used and that is very good.

[pfdietz → Der_Einzige]

Well, as long as they don't delve too greedily and too deep.

[drdeca → Der_Einzige]

> it frustrates attempts to “detect” if LLMs are used and that is very good.

Why is that good?

[Der_Einzige → drdeca]

If you are asking, you’re the kind of person it’s designed to frustrate. Good. Stay frustrated.

[drdeca → Der_Einzige]

Is this an insult, or a criticism?

If you think I’m doing something I shouldn’t, tell me what you think I’m doing that I shouldn’t, and why I shouldn’t?

Why would you just wish me ill?

Note that the FFT has this property of “convolution is pointwise multiplication” for any cyclic multiplicative group, see https://www.sciencedirect.com/science/article/pii/S002200007... for a more algebraic derivation.

Some call this a “harmonic” fft, and there are also non-harmonic FFTs:

- the “additive NTT” of [LCH14] on GF(2^n)

- the circle fft on the unit circle X^2+Y^2=1 of a finite field [HLP24]

- the ecfft on a sequence of elliptic curve isogenies [BCKL21]

On: Group actions and hashing unordered multisets (2021)

[rjeli]

There’s a nice writeup on group hashes here: https://cronokirby.com/posts/2021/07/on_multi_set_hashing/

In particular, if you choose a group where discrete log is hard (such as prime order elliptic curves), multiset hashing falls out for free

With high enough accelerometer accuracy, you need to start adjusting your subtracted gravity vector with maps, right?
